Application July 27, 1948, "SBIiaI'NO. 40,901

This invention is .an improvement in closure caps "for containers; and particularly .a closure that is adapted to be permanently attached-Etc the container adjacent the delivery opening thereof, and is movable to open .or seal the container.

The closure cap of this invention :is adapted for collapsible tubes, of the sort made fo -tooth and otherkinds of pastes, shaving creams, face creams, pasty and concentrated shampoo preparations, "paints, viscous inks, "petrolatum and other substances; but it may of course -be used on containers of a different type.

One object is to provide a closure for permanent attachment; but movable to open :quickly for free emission-of the contents without becomdetached from "the container; and capable when shut of effectually scaling up the latter.

Another object-is to provide a closure of simple construction, but interesting in operation and attractive to the user; as well as inexpensive and easy to produce.

Othe objects will become apparent as the invention is more fully described; and the novel features are-pointed out in the claims.

In the drawings, which illustrate a former this invention:

Figure 1 is a side view of the container with the cap in closed position. I "Figure .2 is a top view of the closure cap.

Figure 3 is a sectional view (taken-along the line 3-3 of Figure 2. r Figure 4 is a sectional view taken along the line 4-4 of Figure 3.

Figure 5 is a view-similar to Figure 3 of a modi- Figure 6 is a perspective view of the closure cap.

Figure 7 is a perspective view of a retainer tor securing the closure cap movably in position on the container.

Figure 8 is a section on line 88 of Figure 3.

Figure *9 represents a detail of a modification.

The container has the form of a tube 1 of collapsible material, its bottom 2 being crimped and the top having a bevelled shoulder 3 with a neck 4. ,.At.th e base of said neck is an inclined groove 5- which runs half way around the neck, said groove being parallel to and having the same depth and pitch as the screw threads 6 which cover the remainder of the outside of the neck.

Above said threads the neck has a convex top I with a peak point 8; thus creating a dome, which has on one side a, delivery orifice 9.

The closure shell or cap l0 likewise has a top 3 Claims. (01. nee-521a tapering to a peak-point H, thus again creating a dome, having on one side an orifice 12 with an inclined edge 13. The cap I10 has the outline of an octagon with slightly concave sides It below the top. "In one side of the octagon opposite the orifice I2 is arecess 15 that receives the retainer clip It. The lower end iii of this clip is bent over and has an upturned projectionor tongue 1'8; and when attached the end 13 enters the groove 5 and the projection 18 abuts the rim 9 of the cap it along the inside. At the bottom :of the cavity or recess 15 is a notch 20; and struck from the element 16 is another projection orispur 21 which enters the notch and engagesa'iong its outer end with .a transverse rib 22. The upper end 23 of the clip is curved to lie flush with the top of the cap ID. has threads terminating just short of the rim 19 to engage the threads '6.

The innersurface of the closure carries gasket 24 in a shallow recess 25 to seal the tube when :the cap is closed. To reduce the cost of molding, this recess :25 begins at the dome above the threads in the cap andextends nearly to the peak 1 1. It has the outline indicated in Figure 2, the curved edge 26 adjacent the threads in the cap being bevelled or inclined to merge with the adjacent surface inside the cap. The opposite edge is near the orifice l2 and has the form of a straight shoulder 21.

The gasket is made of suitable material that can withstand abrasion and is held by an adhesive in the recess 25 to seal the tube fully when the openings 9 and 10 are out of registry. Although this gasket is for the perfection seeker and can be used effectively on any embodiment of this invention, it may also be omitted and thus save its extra cost because the cap is suflicient without it.

To assemble the device the closure shell 10 without the retainer is screwed on the neck 4 and is so designed that when tight it closes "the orifice l2 of the tube I. Then it is turned back nearly to open position in order that the retainer Hi can be attached. This is done by causing the tongue 1'! to engage the inside of the .rim 19 and then fitting the remainder of the clip into the recess 15 and finally pressing the tongue 21 into the notch 20, thus locking the retainer in position, with its end I! slidably fitting the stop formed partly on shoulder and neck or edge of the groove 5. The cap I 0 can be rotated through an are as long as indicated by double arrow arch of Figure 4, but is stopped when the end I! engages either end of the groove, and it cannot The inner suriaceaof the cap be detached as long as the clip is inplace. With the clip at one end of the groove the apertures 9 and I2 register; at the other end the tube is sealed.

A movable pin member is utilized on the mold for the tube for the formation of the groove 5; thus requiring no extra operation. In case the groove 5 presents some difficulty or the precision parts required to produce it are too costly, the neck of the tube below the threads can be made smooth, and instead, an indication can be put on so that either the groove can be ma chined; or a stop in the form of a boss can be formed at the indicated spot on the surface of said neck. This groove can be of such extent as to increase the rotatable movement of the closure ID to half or more of the circumference of the neck 4 if desired.

After the closure is secured to the tube it will complete its full movement from closed to open position in the space of about /7 of the circumference of the neck, for example. Thus after the closure is screwed tight on the tube it moves less than a half a turn to its open position. Its closed position will be at point 28 as illustrated on Figure 4, but the groove Will extend farther to a point 29 to allow for wear.

Figure 5 illustrates a modified form of the device with the neck of the tube in this instance having a thinner portion 39, the size of which suffices for the creation of the orifice 9 by the user.

Another modification can be made by having the retainer l5 shorter, without the curved part 23, to fit only on the area of one of the octagon sides of wall 5. This gives a heater and more compact appearance.

In the Figure 9 the neck 4 is illustrated Without a groove 5, and with a projection or stop 3! at the side thereof, to take the place of the groove. This stop may be formed on when the tube is stamped or pressed or drawn out or attached in any suitable way. The end ll of the clip I6 is just long enough to cooperate with this projection and limit the movement of the cap as before. The cap is screwed on, and when turned into proper position with the recess l5 adjacent the stop 3!, the retainer is attached in the manner above described. The cap is now held in place but can be rotated to open and close the tube without becoming detached. When the cap is turned far enough to engage the stop the openings register; and when turned back to be tightened, the cap closes said openings.

It is understood that the embodiment set forth herein is illustrative only, and not restrictive, as various changes can be made in the construction and arrangement of parts without departing from the essential design of the invention.
